Patent number: 8087748Abstract: An ink jet recording head having a high durability and high ink resistance can enable high-quality image recording by employing a material capable of reducing the internal stress and having satisfactory patterning characteristics. Such an ink jet recording head can be produced with high precision. A cationically photopolymerizable resin composition containing a condensate of a hydrolysable organosilane compound, employed as a material for forming a flow path forming member, enables a reduction of internal stress and a highly precise pattern in the flow path forming member, thereby providing an ink jet recording head having high durability and high ink resistance and capable of high-quality printing over a prolonged time.Type: GrantFiled: January 31, 2011Date of Patent: January 3, 2012Assignee: Canon Kabushiki KaishaInventors: Etsuko Hino, Norio Ohkuma, Yoshikazu Saito, Mitsutoshi Noguchi, Helmut Schmidt, Carsten Becker-Willinger, Pamela Kalmes
